Abstract

Laser diffraction intensity decrease in active muscles precedes tension development at sarcomere lengths below 2.76 microns, but not at greater lengths. This suggests that the time lag is caused by random sarcomere shortenings inside each myofibril.

摘要

在肌节长度低于2.76微米时，活跃肌肉中的激光衍射强度下降先于张力发展，但在更长的肌节长度时则不然。这表明时间延迟是由每个肌原纤维内随机的肌节缩短引起的。
